Simplecom CM303 Ultra HD 3 Way HDMI Switch 3 IN 1 OUT Splitter 4K@60Hz

CM303 is a 3 Way mini HDMI switch that can expand the HDMI input of your HDTV, which can connect more HDMI compatible devices for seamless transitions. Easy plug & play operation, simply connect the HDMI input sources to the HDMI inputs on switch and the HDMI output port to HDTV.

Auto Switching
It will automatically switch to the newly switched on input, or if there is only one active input left. If there are multiple active inputs, you can select the input by press the select button on the switch or use the remote control.

Infrared Receiver and Remote Control
The included infrared receiver and remote control allows the switch to be controlled from a distance. Easily switch between HD devices without having to get up from your seat.

Powered from Connected HDMI Devices
No external power is required to make this switch work, as long as the connected HDMI devices supply sufficient power to the switch.

For warranty claims or issues with faulty/damaged items received during transit, please email us your order number, photos/videos of the fault (and original packaging if applicable), and any missing parts circled in the manual.

We’ll assess each case individually to determine whether to send replacements, issue a refund, or replace the product. Do not return items unless we provide a return authorisation, and note that customer-incurred postage costs are non-refundable without approval.

Email us within 14 days of delivery with photos/videos and your reason for return, but don’t ship it back without our guidance.

Refunds deduct a 7-25% restocking fee and return postage (if applicable), with return-to-sender refunds processed after warehouse receipt.

For missing or damaged parts within the 12-month warranty, email us your order number, manual with issues marked, photos/videos, and a brief explanation.

We’ll decide on replacement parts, refunds, or product replacement, providing a return label if needed, no returns without our instruction, and postage costs are only refunded with approval.

Shipping Guide - Seamless Delivery of Your Orders

Orders are generally shipped from our distribution center in Melbourne within the 1 to 2 working days after full payment has been received. Auzzi Store collaborates with leading courier partners, including Australia Post, Aramex, Allied Express, Toll, and Hunter Express, to ensure efficient and cost-effective deliveries. Estimated delivery times vary by location, ranging from 3-5 working days in VIC to 7-10 working days for QLD, NT, WA, and TAS.

In some cases, parcels may be returned to us due to inaccurate addresses, unsuccessful delivery attempts, or refusal by the recipient. If a parcel is returned, our customer service team will contact you to arrange re-delivery, which may incur additional costs. For failed deliveries via Australia Post, a collection notice will be left in your mailbox, while Aramex and Allied Express will schedule deliveries in advance. To prevent rejected shipments, please ensure gift recipients are aware of their package arrival. Additionally, certain remote postcodes may not be serviceable, and extra shipping fees may apply. If your item has not arrived within ten business days, please contact our support team for assistance. While we cannot guarantee specific delivery dates, we will communicate any unforeseen delays and offer solutions, such as replacements or refunds, if necessary.

To maintain an efficient dispatch process, self-pickup and third-party courier arrangements are not available at our warehouse. In the event of significant delivery delays, we will initiate an enquiry with our courier partners, which may take up to two business days. If no resolution is provided within that timeframe, we will offer alternative options, including refunds or replacements.
